Abstract
The utility model provides a parallels for heat treatment furnace, this scheme is including the parallels body and the logical groove of setting on the parallels body, the positive cross sectional shape of the parallels body is square, the cross sectional shape of parallels side face is isosceles trapezoid, it sets up the lower part at the parallels body to lead to the groove. This scheme adopts the refractory material preparation, and structural design simultaneously has logical groove and high temperature resistant layer, can reduce parallels weight, can have higher heat resistance simultaneously, prevents parallels height temperature heat altered shape, has higher life.
Description
Technical field
The utility model relates to fire-resistant parallels, a kind of parallels for heat-treatment furnace.
Background technology
In the prior art, known technology be the parallels in existing industrial furnace all be use heating resisting metal material make, its heat resisting temperature is the highest, being prone to oxidation simultaneously, be all monoblock molding additionally, due to parallels, weight is bigger, use cost is higher, and this is the weak point existing for prior art.
Utility model content
The purpose of this utility model, it is aiming at the deficiency existing for prior art, and the technical scheme of a kind of parallels for heat-treatment furnace is provided, the program uses refractory material to make, it is designed with groove and high-temperature-resistant layer in structure, it is possible to reduce parallels weight simultaneously, can have higher thermostability simultaneously, prevent parallels height warm and hot deformation, there is higher service life.
This programme is achieved by the following technical measures:
A kind of parallels for heat-treatment furnace, includes parallels body and the groove being arranged on parallels body；The cross sectional shape in parallels body front is square；The cross sectional shape of parallels body side surface is isosceles trapezoid；Groove is arranged on the bottom of parallels body.
Preferred as this programme: the quantity of groove is at least one.
Preferred as this programme: the top of groove is arch.
Preferred as this programme: the top of parallels body is provided with high-temperature-resistant layer.
Preferred as this programme: the height of groove is less than 1/2nd of parallels height.
The beneficial effect of this programme can be learnt according to the narration of such scheme, arranges arch groove owing to using in this scenario, can either ensure parallels intensity, can reduce again parallels weight in parallels body；Arranging high-temperature-resistant layer at parallels body top, parallels and boiler high temperature region can either be made to have certain isolation, be prevented from again parallels oxidation deformation, use refractory material to make parallels body more cheap compared to refractory metal material simultaneously, cost of manufacture is lower.
As can be seen here, this utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent from.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model detailed description of the invention.
Fig. 2 is Fig. 1 side view.
In figure, 1 is parallels body, and 2 is groove, and 3 is high-temperature-resistant layer.
Detailed description of the invention
For the technical characterstic of this programme can be clearly described, below by a detailed description of the invention, and combine its accompanying drawing, this programme is illustrated.
By accompanying drawing it can be seen that this programme includes parallels body and the groove being arranged on parallels body；The cross sectional shape in parallels body front is square；The cross sectional shape of parallels body side surface is isosceles trapezoid；Groove is arranged on the bottom of parallels body.The quantity of groove is at least one.The top of groove is arch.The top of parallels body is provided with high-temperature-resistant layer.The height of groove is less than 1/2nd of parallels height.
This programme material is the prefabricated molding of the refractory casting adopted and make high strength at high temperature, and the castable refractory of this high strength at high temperature is low-cement refractory pouring material, has the resistance to elevated temperatures relatively solving parallels；For improving its elevated temperature strength, structure is designed to rectangle, and its cross section is trapezoidal；Owing to sectional dimension is relatively big, for solving the thermal stress that at high temperature produces and alleviating weight, in the case of meeting requirement of strength, bottom has more than one hole slot, thus extends the service life of parallels further；Can according to difference use require and different size require carry out prefabricated, easy to make fast.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
